Bynes, who made a name for herself as a child star on Nickelodeon's sketch comedy show, "All That," is currently facing a DUI charge from an April arrest, two hit-and-run charges, as well as a charge for driving on a suspended license (police impounded her BMW in mid-September).

Says an insider close to the troubled star, "Amanda is spiraling out of control. She won't accept help from anybody ... She's completely lost."

Lohan, for her part, has certainly had her share of legal troubles in recent years: "The Canyons" actress is on probation through May 2014 for her 2011 theft of a $2,500 necklace. In March, her formal probation from her 2007 Beverly Hills, Calif., DUI case came to an end.
